AlertDialog.Builder alertDialog = new AlertDialog.Builder(Borc.this);
// Setting Dialog Title
alertDialog.setTitle("Eraser");
// Setting Dialog Message
alertDialog.setMessage("Are you sure?");
// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.remove);
// Setting Positive "Yes" Button
alertDialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dataBase.borclar.delete(String.valueOf(tableHelper.getSelectedRowId()));
}
});
// Setting Negative "NO" Button
alertDialog.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
// Showing Alert Message
alertDialog.show();
在任何需要显示对话框的地方使用此代码
AlertDialog.Builder builder =new AlertDialog.Builder(Dialogs.this);
builder.setIcon(R.drawable.save1);
builder.setTitle("Save Your Work");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do something.......
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do something.......
}
});
AlertDialog alert = builder.create();
alert.show();
我认为使用android对话框的最佳方式是阅读文档:。它们描述了各种类型的对话框以及如何在应用程序中实现它们
如果您有特定问题,请向我们展示您的代码并提出正确的问题。您有什么问题?你能详细说明一下吗?非常感谢………..:)您可以下载图像以添加到对话框..public void onClick(View v){DB.open();Cursor c=DB.getContact(“1”);if(c.moveToFirst()){do{Display(c);}while(c.moveToNext());}DB.close();String checkPass=pass.getText().toString();if(checkPass.equals(getpass)){startActivity(newintent(Welcome.this,Main.class));}else{Toast.makeText(getBaseContext(),“错误密码”,Toast.LENGTH_LONG).show()}
